I don't think any bref description here will help in your daily work, I think you need to seek for information/help more nearby.
- SAS Production Software Deployments (Adding another sas product in production servers),
Depends on which product you wish to add. If it's a Foundation product, usualy, you you just install it. SAS tech support or SAS professional service could be of help here.
- SAS Upgrades Production and Development servers
What do you mean by upgrades? SAS version? See the migration pages on support.sas.com.
- SAS Server Capacity Planning
Performance and capacity planning is an ongoing discussion almost everywhere. If you don't have the means at your site, SAS professional services, or a SAS partner usually can help you in this area.
- SAS Server Backup Strategies
Well, you probably need backup, but how, when etc depends on the nature of your application and your server and backup system. Again, SAS or a partner can help you in these discussions/planing.
